I've been here a couple times, especially during late hours when I want a bite to eat. I enjoy their beef tongue and their brisket. The service is okay, the workers can look a bit angry but I think that's just how they are. Other than that, the food is good and cheap. If you leave a lot of left overs, they can charge you a lot. So be careful and if you want just a little more, ask for only a little otherwise you won't be able to finish it all and be charged extra.
If you're planning to eat here after 10, expect to wait about half an hour for a seat because it gets pretty packed.
